when i drive at a high rate of speed and have to slow down quickly my brakes make these wierd screeching sounds when i brake? i was thinkin if that was the abs or if my brakes were just heating up from high speeds

 

i'm hearing this short screetching noise too from my front brakes recently when i stop suddenly. i don't even have to be going that fast. even if i'm going like 10-20 mph in a parking lot and hit the brakes hard, i hear this noise. haven't figured it out yet. any ideas anyone?
